Detailed Description

Convert one TBFsolver output folder's statistics into the same NPZ `run_channel_18.py` writes.

  python tbf_profiles.py <TBFsolver output folder> [--ny 160] [--out tbf_profiles.npz]

TBFsolver's statistics (`src/statistics/statistics.f90`) are TIME averages of PLANE integrals,
divided by the slice volume — so for the region `R` (`_W` whole, `_G` gas, `_L` liquid, with the
weight `cv` = 1, `c`, `1 − c` and `c` the GAS fraction, the same convention as our transcription):

    stats_c          <c>(y)                                       1 column
    stats_u<R>       <cv ux>, <cv uy>, <cv uz>,                    9 columns
                     <cv uxux>, <cv uxuy>, <cv uxuz>,
                     <cv uyuy>, <cv uyuz>, <cv uzuz>
    tauw             the time-averaged wall shear stress

They are NOT conditioned averages: the liquid mean velocity is `<(1−c)u>/<1−c>`, which is what this
script forms, exactly as `run_channel_18.py` does with its own `L`-weighted sums.  Both codes'
NPZ therefore carry the same quantities under the same names and the plotting script can overlay
them without further arithmetic.
